Jasmonic Acid Levels and Seed Development in Sunflower (helianthus Annuus L.)
نویسندگان
چکیده
Using gas–mass chromatography analyses (GS-MS) we have determined the endogenous levels of jasmonic acid (JA) in developing sunflower seeds. The level of JA was higher in the early phases of seed development. We have registered a maximum on day 5 after pollination. Spraying of plants with JA at the time of flowering induced marked changes in protein content. Five days after treatment total protein content decreased by 33% whereas 15 day after flowering it exceeded the control values by 33%. In addition, the results from the SDS-polyacrylamide gel eletrophoresis (SDSPAGE) revealed qualitative and quantitative changes in the spectra of soluble proteins.

Abscisic acid content of a nondormant sunflower (Helianthus annuus L.) mutant
A sunflower (Helianthus annuus L.) mutant was observed in the progeny of a cross between the sunflower cultivar HA 89 and an amphiploid of a H. divaricatus L. × P21 cross that exhibited loss of dormancy induction in the developing embryo. Seeds of this mutant frequently germinate on the head about 40 d after pollination (DAP). In contrast to other nondormant sunflower mutants reported previousl...

Modifications of the fatty acid composition of plant vegetative tissues produce deficient plant growth. To determine the expression of the seed high-saturated sunflower (Helianthus annuus L.) mutant character during the vegetative cycle, five sunflower mutant lines (three high-stearic and two high-palmitic) have been studied during their germination and vegetative cycle. No significant variatio...
متن کاملOverexpression of a gene encoding hydrogen peroxide-generating oxalate oxidase evokes defense responses in sunflower.
Oxalate oxidase (OXO) converts oxalic acid (OA) and O(2) to CO(2) and hydrogen peroxide (H(2)O(2)), and acts as a source of H(2)O(2) in certain plant-pathogen interactions. To determine if the H(2)O(2) produced by OXO can function as a messenger for activation of defense genes and if OXO can confer resistance against an OA-producing pathogen, we analyzed transgenic sunflower (Helianthus annuus ...

Abstract In order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. Treatments were a combination of three levels of drought ((100, 60 and 30 percent of Field Capacity (FC)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a Completely Randomized Design w...
